Abstract

Este trabajo se inserta en el desarrollo de los proyectos de estructuras cilíndricas presurizadas, evaluando y complementando los
recursos existentes para el proyecto de superficies de revolución sometidas a presión externa y considerando las formulaciones
analíticas que toman en cuenta los comportamientos no lineales, tanto geométrico como físico, importantes cuando se desea verificar
el colapso de este tipo de estructuras.
Con este trabajo se pretende la aplicación de métodos probabilísticos de análisis de resistencia al caso de estructuras en forma de
superficies de revolución sometidas a presión externa. Para cumplir este objetivo serán determinadas las cargas críticas con la
formación de lóbulos circunferenciales según la teoría de Reynolds, tomando en consideración las variaciones de algunos parámetros
geométricos que influyen en esta carga.


Palabras claves: Estructura, estabilidad, falla estructural, imperfección geométrica, superficie a presión.

Abstract:
This work is inserted in the development of the projects of cylindrical structure under pressure, evaluating and supplementing the
existent resources for the project of circular cylindrical surface under external pressure. In the same are considered the analytic
formulations to take into account the non-linear behaviours, (geometric and physic) when is necessary to verify the collapse of this
type of structures.
The application of probabilistic methods of resistance analysis to the case of structures with shape of cylindrical shell under external
pressure is sought. To complete this objective the critical loads are determined according to Reynolds’s theory taking into
consideration the variations of some geometric parameters with influence in this load.


Key words: Structures, stability, structural failures, imperfections, cylindrical shell under external pressure.
